Most children will be eleven when they sit these tests, but some summer-born children may still be ten years old when they sit their SATs.
These tests are designed to assess students' educational progress near the end of Key Stage 2 (KS2).
The subjects tested typically include Maths, English Reading, English Grammar, Punctuation and Spelling (GPS).
The results of these tests provide a snapshot of a child's academic performance and understanding of the KS2 curriculum.
